" 3 Claims. 101. 120-75) 2 This invention pertains to pen holder caps with ink containers.

One of the objects of my invention is to provide a fountain pen cap which has an ink reservoir in its top with a closable opening from which the pen may be filled, and has a base which will support the cap in a stable manner when the reservoir is opened.

Another object of my invention is to provide a cap for fountain pens or the cases of other pens which are carried in the pocket of the user which has a longitudinal bore in its lower part adapted to fit over the pen grip, a reservoir in its upper part adapted to contain ink, and an exterior including at least one flat surface positioned opposite a radially extending access hole which is closed by a screw cap, or the like, so that-the cap may be placed and substantially retained on a level surface where it will support itself with the access hole uppermost and will not tip over.

Another object is to provide a fountain pen cap with an ink reservoir in its upper part which has a radially extending access hole closed by a cap and an outer surface having a flat face opposite said hole forming a base on which the cap may rest in horizontal position.

A still further object is to provide such a cap with an access hole having a neck including a raised rim which is threaded to receive a closing cap and is provided with a clip adapted to secure the cap to the edge of the user's pocket.

Other objects will appear hereinafter.

I attain the foregoing objects by means of the devices and construction illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of one form of my improved pen cap;

Figure 2, a front elevation thereof;

, Figure 3, a bottom end view thereof;

Figure 4, a vertical section taken substantially on lines 4-4, Figure 2, but with the cap placed in a horizontal position and with the drawing made on an enlarged scale; and

Figure 5, a side elevation of the pen cap when opened and used as an ink well.

Similar numerals refer to similar parts in the several views.

In the drawings, 2 indicates the body of a pen cap adapted to fit over and onto the end of a pen barrel indicated by dotted outline 3. When this cap is positioned with its length extending vertically, as shown in Figures 1 and 3, 4 will indicate the lower end. This portion has a cylindrical bore 5 adapted to receive and fit over the end of pen -3. Within the upper portion 6, and.

separated from bore 5 by a partition 8, is an ink reservoir I0. Access is had to this reservoir to receive a closing cap l6.

Opposite upper side [4 is a fiat faced base side Hi. This may be termed the base side for the reason that when .the cap body is removed from the pen, it may be positioned horizontally as shown in Figure 4,, and will then rest on any horizontal surface. Base side l8 will then act as a base and will support the cap body with the side :4 uppermost. In its preferred form the cap body has an approximately square, transverse section. The pen cap body may, however, have other prismatic or even semi-cylindrical forms. But in any case it is always necessary, in order to carry out the purposes of my invention, for it to have a fiat base side, such as [8.

Nipple I5 is placed as near to the upper end of cap body 2 as possible, and a partial partition 2| along the olwer'edge of hole I2 may extend into reservoir I0 to form a well, or filling area 22, somewhat separated from the rest of the reservoir. The upper end -6 of the body 2 is smoothly rounded and the lower end somewhat tapered at 24 to join the rim of bore 5.

Closing cap I5 is made of suitable material, integral with clip 26. Its under side is bored and threaded to screw onto nipple IS. A rubber gasket 21 is placed in the upper end of this bore. This provides an eifective fluid-tight seal between the cap and nipple l5. When cap [6 is screwed tightly on the nipple the clip will extend downward along side M and parallel with the axis of the cap body. When cap I5 is to be unscrewed the lower end of the clip may be swung rotatively as indicated by dotted lines 26a, Figure 2. The clip thus acts as a handle to tighten and loosen the nipple closing cap [6, as well as forming a means for retaining the cap and pen on the edge of a. pocket or the like.

In use, the reservoir IE1 is filled with ink and the closing cap l6 screwed on nipple :5. The cap body Ill may then be applied to the nib end of a fountain pen 3. The reservoir then provides a convenient supply of ink which may be treated as a reserve, and used to fill or dip the pen should it unexpectedly run dry. If desired, a plain pen holder and steel pen may be substituted for the fountain pen and the reservoir used as an ink well. be opened it is removed from the pen and posi- When the reservoir is to 1.
